| Adding chelating agents could reduce the REE uptake of one accumulator fern, whereas no effect was observed for non-accumulator species (Ozaki et al., 2002). A linear accumulation of REEs with increasing plant age was found for Norwegian spruce (Wytternbach [sic!] et al., 1994), a fact that is important when studying perennial cops [sic!]. Relevant for plant uptake in this context is also whether REEs are naturally abundant or exogenously applied. So, 81–97% of the applied La was plant available but only 25–56% of the naturally abundant element (Stokes et al., 2001).
